Ah, you do get the PF in a Diesel-version over there?Captain caveman wrote:Hello and welcome the site. I'm a diesel mechanic here in the states. On our 07 and up diesels the all have DPFs. I'm very informed to the DPF systems. You can not remove the DPF with out the ECm throwing codes for Aftertreatment filter pressure inaccurate, DPF will not regen and many more. Do not remove it, just let it run its regen and be happy.
Running high sulfur diesel with the DPF will cause major DPF plugging issues in very short order. We had this problem in the US in 2007, as ULSD (ultra low sulfur diesel, LT 50ppm sulfur) was not widely available in the beginning of 2007. Many DPFs had to be replaced (=expensive!)Captain caveman wrote:Hello and welcome the site. I'm a diesel mechanic here in the states. On our 07 and up diesels the all have DPFs.

I would imagine they are not just O2 sensors. There is a delta-p (pressure) sensor before and after the DPF to detect the soot load in the DPF. These would need to be replaced with the 'fooling' sensors to keep your vehicle from attempting regeneration.sashasolar wrote:Hi Guys! Thank you very much for your comments!
Yes, we've been thinking of bringing our car back to Europe (France) and selling it there. But it'd be a crazy task to drive Armenia-Georgia-Turkey (ARM-TR border is still closed) - boat to Italy - France. Custom clearing it in France, then trying to sell... at a big loss of course.
Local dealers do not sell diesel cars in Armenia due to poor fuel quality here. I know, we should have done more home work before bringing the car here...
Basically, we have to either remove DPF and install the O2 sensor simulators to fool the system or to sell the car in EU.
It will not be illegal to use the car here without DPF.
There are O2 sensor simulators on sale on a popular online auction;-). The item descriptions look good....
What if we remove the DPF and plug those simulators instead of the sensors, so the Engine Check does not come up?
The other confusing thing is that I can see three sensors attached to the DPF: one before the filter and two after. Does anybody know what each sensor is responsible for?
In the service manuals we saw, there are two sensors shown... What is the story with the third one? I took photos of these sensors, I wander shall I share them with you guys?
Thank you for the link to the Russian Nissan forum. I asked them for heads up also, but with no result still. Some recommend O2 simulators, some say I need a "resonator" (no idea how to translate this one into English).
To summarise my essay:-) What are your views on removing DPF and replacing the o2 sensors with simulators? And why are there three sensors attached to DPF on 2008 2.5L TDi Pathfinder
No you'd need a diagram of the exhaust setup and the sensors to be labelled. I've never seen one for a diesel. Perhaps you can buy through a European Nissan dealer?sashasolar wrote:Thanks Terry! Is there any way to confirm whether these are o2 or pressure sensors? I am looking for a Service Manual for 2.5L TDi, but with no luck...
